I '0 all who-m it may concern:

Be it known that I, THOMAS P. WALSH, a citizen of the United 'States, residing at Vorcestcr, in the county of Worcester and State of Massachusetts, have invented an fahric, the complete loom being shown and claimed in my copending application, Sei.

No. 429,297, and the present case covering the coiling, linotting and looping mechanism broadly without reference to a com pact, Woven (properly socalled) fabric.

.l do not intend to restrict my invention to the formation of,the particular kinds of knots commonly found in Oriental rugs, as my invention is applicable to a much wider range of products, being in fact readily adaptable to all varieties of fabrics contain-. ing warp and weft and inwhich it is de-, sirablefithat the two shall beimmovably connected at various intersecting portions throughout the fabric. I

lv' y invention will be more clearly and fully understood from the following detailed description of several illustrative embodiments of the invention which I have devised as preferred forms of mechanism for weaving slightly different varieties of.

products.

Before entering Upon the detailed dcscription,.it may be well to point. ventionis broadly distingui vious attempts to Weave aout that my inshed from preknotted pile fabric, in that it knots a weft on a warp, as distinguished from knottnn. a warp on a Weft. As a result,

I am enabled to use one and the same thread, thrown from a shuttle or any other means, to form do not intend to limit mvscl and all transverse pile thre s i m ult a neously all the piles entirely across the fabric. I

f in any Way to the means of putting the shot or pick of weft (by which term I mean to include any ads)v across the' loom, as it may be by a shuttle, eye needle, nipper needle,-or what not. For clearness of presentation of. my invention, in its roader aspects, I have shown the simplest kind of embodiment, viz. aloom making fabric for chenille, fringes, and the like, in which the weft is formed around all the contiguous warp threads, but I wish it u11- derstood that my invention, as hereinafter broadly claimed, is not limited in the latter respect.

' .rectcd bet-ween transverse 20 at the rear of naled or held in forks 13, and a let-off drum 14 journaled'at in the roll 12 occupies at by the'warps. are held in proper frictional geared take-up roll 22,

machine and pivoted I '31 at the forward end'of'the machine, said In the present construction the warp threads 1 may be considered to all intents and purposes as endless, i. 'c., they have no definite beginning or end, but the fabric as it is woven is rolled or gathered forward continuously, so that the loom 'is capable of weaving a product of indeterminate length. A usual warp beam 2 .is looselyjournaled at 3 in the loom sides 4, having preferably its tension delicately adjusted in usual manner by a friction strap 5 fast at (3 to the journal box'at one side of theloom, the ends of said strap 5 being yieldingly adjustable by'a spring 7 and nut 8 on a threaded bolt 9 provided at its opposite end with '.a handle 10 having a releasing cam 11 normally in clamping position, as shown in Fig. 1. From this warp beam 2 the warps 1 are led over a guide roll 12 which is loosely jourthence about loom sides, preferably positively actuated by. let-off mechanism to be described, aguide roll 16 similar'to the guide roll 12 being mounted in similar forks 17 and preferably arranged on the outgoing side of the let-off drum in about. the same position-that the the ingoing side, whereengagcment with the l'et-off'driumand dirods 18,. 19, for easing the warps periodically to permit the knotter 20 to perform 'its operations to the best advantage. From the roll or easing device l8, 19, the warps pass to the knotter the, loom, and from the knotter pass forward preferably horizontally over the breast beam 21 to a usual guide roll or pressure roll 23, 'to a final take-,iip roll 24, and thence the finished productimay; be deliavered to the floor. or a windingmachine or any-otherplace or m hanisrn desired, said tal-:eu p mechanism being "preferably operated from the same maindriving shaft 26' which operates all the ,ca'm niechanism or other moving means provided foractuating the loom, said' tal'ce-up i'nechanism being herein shown as-actuated byajlink or rod .127 'iltljHStfllJl-Y securedat" 2810 a crank 29 fasten the shaft-2G at the rear end of the at 30m a pawl arm '41, whose pawl 42 with a pinion the drawings,

The-let-off, as already stated, is positively operated the same as the described Connected to the same crank 29 already mentioned is a' link or rod 38 piv oted at 39 to a pawl arm 40 loose on a shaft engages a ratchet wheel 43 fast on the outer end of said shaft 41,

is secured, said 35 meshing withtake-up just i whichv drives a gear 44'at the opposite end of said shaft 41, said gear 44 being in .mc'sh fast on the shaft '15 to which the let-ofi' roll 14 issecured. T

The knotter20 comprises, in the deviceof a shaft-having axially rotary an offset. portion 47 and pro series of warp carriers 48' each,

ends 46 and vided with a arch shaped in form, as best shown in Figs.

1, 2, 9, l1, and 13. Each Warp carrier may manipulate fw'o war Figs. 914, and fort iis purpose is" provided with holes or thread-eyes'49, 50, for one" Warp, and 51,52, for theother warp, tli'e rcspectivejwarps being-threaded through said eyes as shown in Figs. 9-18, as, for instance, one warp thread is threaded through the eye 49 from the near side Figs. 1, 9-14,- and-thence is led downrthe art-her side of the warp carr er to the eye '50, through which it is passed backfagain andthence at 53, over the breast beam 21 to the take-up roll, and its comthreads, as shown in I panlon warp is led upwardly along the rear side of the same warp through thejeye 51 to the warp carrier, ig. 9,'and"tl'1en'eedown and ye- 52 to the rear side again of said warp carrier and across itself to the carrier and threaded near side of said breast beam 21 and tal re-uprol-l, so that the diagonally upwardly extending strands of the two warps from the casing rods 18,19 pass between the horizontal strands or portions of said warp threads as the latter are carried forward to the breast beam-. I lprefor to pass the r position shown in Figs. 1, 2, and'9 to the position shown in Fig-13. When the parts are-in the position shown in Fig. 9 a sufficient dwell is' given for the passage of the weft or filling thread, which maybe accornany usual or preferred mechanism, and accordingly I have herein simply plishcd by two :ho rizontal portions of '.tl1e two warps outside of the upwardly exindicated a usual shuttle 54 driven by a picker stick 55 connected by a usual picker stick connector 56 to an arm 57 actuated by a shaft 58 and picking shoe a9 and picking ball 60 on an arm 61 fast on the main driviug shaft 26, all in usual manner.

In connection with the passage of the shuttle or rather the proper placing of the weft thread, by whatever mechanism it may be placed, whether shuttle or not, it is necessary to provide some means for preventing the weft thread from remaining taut, and accordingly as a convenient means of accomplishing this object, I provide a series of needle-like devices for engaging the weft thread at a plurality of places throughout its length across the loom and pulling it transversely so as to provide said necessary slack. To this end, just before the shuttle accomplishes its transverse movement above described, I raise a series of needles 62 from the dotted. position shown in'Fig. 7 to the full line position shown in Figs. 1 and 7. Said needles are slidingly mounted at 63 in the pivoted hub end 64 of a plate (35, which serves not only to swing the needles as described, but, because of its plate shape, to direct the needles in their subsequent backward movement. This movement is accomplished by a cam 66 arranged to reciprocate transversely of the loom on a shaft 67, said cam being shown best in Figs. 1, 4 and 30, and arranged to enga e the forks 68 provided at the rear ends of the respective needles. By this means the needles are drawn rearwardly successively and serve to pull the weft thread transversely across the warp carriers so as to introduce the requisite amount of. slack into the thread. The reciprocating movement of the cam 66 is given by a cord or band 69 to which the cam 66 is fastened at 70, said cord being guided by guide wheels 71, 72, 73, and driven by a drum 74 provided with a pinion 75 operated by a rack 76 actuated by a crank arm 77 extending from a shaft 7 8 driven by a pinion 79 in mesh with a mutilated gear 80 fast on the main driving shaft, said mutilated gear and its pinion being so proportioned and constructed as to give the requi-' I site dwell at the end of the slack producing motion to permit the knotting movements to take place before the return movement of the slack producing cam; The needles when in their initial horizontal position also constitute a convenient supporting track or raceway for the passage of the shuttle. vThis is not essential but, in view of the fact that the warps are led around in a. loop, or

in other .words each Warp is looped over and held open while the weft is passed through 'it, it is desirable that the shuttle should have a stronger support than merely that of the warps. As soon as the shuttle 54 has shot under the arch of the warp carriers, and hence through the warp loops just mentioned, formed in the body of the warps by the position of the warp carriers at the moment, said warp carriers are reversed in position by the rocking of the shaft 46 over to the left, see dotted lines Fig. 2. As the shuttle thread has been deposited within the two warp loops provided by each warp carrier 20, the result is that when the latter carries one terminal of each warp loop around under said shuttle thread or filling it forms a coil in each warp about the filling thread, but as the warps are comparatively taut and the filler is slack, the warp immediately straightens out, thereby compelling the filler to assume the coiled shape and virtually transferring the coil or loop of each warp thread to the adjacent portion of the filling, with the result that the latter is thereby coiled around the two warps by two coils, the filling projecting upwardly from between said warps. This double. coiling constitutes the knotting referred to, and is exactly the same kind of a knot that is tied by hand in the Turkish or Oriental rug. The operation will be better undcrstood'viewing Figs; 94 i, wher it is shown in detail. I have designated the two warps as a, b, and the weft as c. In the position Figs. 9 and 10 the weft is shot through the arch of the knotter 20, leaving the weft in the position m, whereupon the needles 62 pull the weftback tight into the corner far as it can go toward the right, Fig. 9 as shown at 0, Figs. 9 and 10, and thcreupm'i the shaft 47 rocks, swinging its offset portion so as to move the carriers about theirfree ends as a ccnter, the first portionof said. swinging movcment placing the parts as shown in} Figs. 11 and 12, at which time the needles 62 have released the drawn back weft, which is then held as shown in Fig. 11 by the forwardly extending strands from the eyes 50, 5:2 with the loop over the edge of the carrier. At this moment the reed or comb (presently described) is just getting ready to operate,

and as the knotter continues its movement to the position Fig. 13 the reed engages the weft and shoves it fr in the carrieu lh forward along the two warps or. which it is now knotted as shown in Figs. 19 and 29. A specialrced. now heats up in usual man ner, and the warp carriers 48 are returned to their original position by the reverse rocking 'of the shaft 46.

The rocking movement of the shaft 46 and the swinging action of the carrier or knotter 48 may be accomplished by a wide variety of mechanisms, that herein shown consisting of a rack 81 meshing with a pinion 82 fast on the shaft 46, said rack being pivoted ,to a swinging arm 83 at 84, operated by a path cam 85 in which a roll 86 of swing downwardly,

to the left just sutliciently to provided with path cam 93 en the shaft 26,.and n order said arm travels, To permit the requisite loop-making and swinging moven'ient of the knotter, and yet maintain tautthe horizontal extent of warps 1, I provide the casing mechanisin with movements timed in such a manner that as the warp carriers 48 start. to

1 and 9. the casin redslS 19 swing back prevent any slack occurring in the .war'ps, and as the warp carriers 48 move farther around iii their swinging movement,- the easing bars more back to the right until they assume an approximately verti al position, at which time the warp carriers iSfhave com leted. their-swinging n'im'enient; around t n or to the right-and are ready to return, where-- upon as they return the easing bars swing again to the left until the carriers 48 have nearly reached then-original position, and as they move up finally into their original position the easing bars swing back to the position shown in Fig. 1. the timing ot the. movements is such that the easing hars simply.maintain the same tension at, all times on the warps. To effect. this ino\'eliieiit of the easing bars, .l have mounted them on arms 57 pivoted loosely on the shaft 15, and eomieeled by a swii'eled block 88 to a red 89 pinned ton ieiiiber 90 slotted at Ji -to straddle the shaft 26, and a m roll 92 traveling in a that-the easing bars may be. capable. of gi\'{ in; away tilfyielding whenever necessary, I ha\'e conneeted the-bloek 85 to the rod 39 yieldingly 'by passing said .rod loosely through the swivel blnek'and providing opposite springs J l, $.75 on said rod, hearing at tlipir adjacent ends on the swivelblock 8S and at their opposite ends respectively on adjustable eolla'rs JG. For instance, the easingdiars miist'. yield in case the. take-up takes up faster than the letoll' roll lets oil the. warp, or in ease the shuttle should lodge in the knotter. herein shown, the beating-up reed con ists-of a usual reed or comb 9h whose l'raiiiettt) is pivoted at [00 to the loo-iii frame. and operated by an iii-iii 101 to whieli' is pivoted M102 a'linkltlil pivotiilly eonneeted :ittil-l to a swi ii' ing arm 105 actuated by a rain roll ltlt'i travelinsr in a cam path 107 shaft. 26. etc. is such are swung around 'iipward into their extreme whose eaiii isfaston the mam The shape of the warp carriers, that when saidwarp carriers under to the. right; and ])0Sltl0n, as

' My invention makes it practicable to tie knots continuously, if desired, in this shut.- tlc thread, as it, is moved back andfl'fortli on successive picks, and tomaintain the weaving properly certain at all wish especially to emphasize a further inipoi'tant advantage and novelty resulting from tliisform of mechanism, namely that by it's aid 'th'e pile is formed of filling or piles or ile loops throughout the entire width of the fabr ebeingwoven is made from a sin-. gle fill ng or weft,

This is especially serviceable, as. already intimated. iii accenr plishing'a wide variety of wearing ctfects which have either been heretofore. exceedingly expensive or ble, aspfor instance, by introi'liieing a shedding motion and another pieking notion in order ltilllll'OtltlCt, the ground filling, this loom will weave superior corduroy or pile fabric in which every-pick of loops is cut, and in which each pile is bound or knotted, as distinguished from the present. corduroy or pile fabric, in which a plurality of picks must be left without. being cut, in order to bind or hold secure the OlllQPplCkS which are cut to form't'he pile fabric. lnother words,- my pl'tSQtllJnLt'htl nism is useful in connection with the manufacture of any and all kinds of pile. fabrics so that each pilewill be knot-ted in place;

i in case the loom does: not instantly stop, I

No claim is made to the protection mechanism. as such me hanism is common in looms.

The operation o the loom has already been descrihet in c nnecrir-n with the mechanism. Slated in general, it consists in forming a, loop in each warp thread. or in those warp threads on which the weft is to be secur d. then passing the weft thread through said loops. and atthe same time providing the desired amount of slack'in said wctt thread required, then straightening out the warp threads. causing the knotting coils to form in the weft about said Warp threads. and linally beating up the knotted loops. The slacle producing mechanism preferably so constructed that the needles begin to draw in the slack as soon as the Shlltilt has passed the first needle, so that when the shuttle has rcachedthc end of its pick the slat-l; has already begun to be provided. lVhen th shuttle goes back in the opposite direction. the needles operate in a reverse order, thereby greatly facilitating the speed of the slaclr-producing operation. I wish it understood. however. that I am not limited to any mrticular means of producing this slack. nor in fact to producing it independently of the shuttle, as any means which results in causing the shuttle to throw out or give up more thread oiyarn than it would naturally give up comes within the spirit and scope of this. part of my invention.

As alremly stated. the fabric when out produces av valuable product for fringes and ornamentation of other fabrics, and as the importance of this feature of my invention (aside from its use in connection with rug weaving) renders it of much value. I wish it understood that the use of said product is varied and extensive, including such ornamental work as portieres, piano covers, quilts. dresses, table-cloths. rugs. tidies, chair-covers. etc. where chenille or fringe work is required. For instance, it is useful when used for delicate silk or cotton. or worsted fringes, or in fact with even the coarsest of hemp or jute yarns, especially in color combinations and intricate pattern work, which is rendered extremely practicable by this machine.
